Spatiotemporal Pattern of Ice Concentration in the Chukchi Sea
Russian Meteorology and Hydrology, 2020The seasonal and long-term variability of sea ice concentration in the Chukchi Sea in 1997–2016 was analyzed using all available satellite data on sea ice conditions. It is shown that the zone of maximum variability is situated in the areas with the ice concentration equal to (4–6)/10 and follows the displacements of this area: it moves to the north in

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
This paper assessed the accuracy of four passive microwave (PM) sea ice concentration (SIC) products in polar regions by using twelve scenes MODIS images under clear-sky conditions. The SIC products include the DMSP SSMIS with Arctic Radiation and Turbulence Interaction Study Sea Ice (ASI) algorithm (SSMIS/ASI), the GCOM-W AMSR2 with NASA Bootstrap (BT)

Towards Improved Mapping of Sea Ice Concentration and Sea Ice Thickness with SWOT
Observing sea ice concentration (SIC) and thickness (SIT) remains a key challenge for climate monitoring and modeling. Satellite altimetry provides measurements of ice and sea level anomaly from which can be estimated SIC, sea ice freeboard, and ultimately SIT.Metref, Sammy +5 more

Climatic trends of sea surface temperature and sea ice concentration in the Barents Sea
2021<p>Sea ice loss in the Arctic region is an important indicator for climate change. Especially in the Barents Sea, which is expected to be free of ice by the mid of this century (Onarheim et al., 2018). Here, we analyze 38 years (1982-2019) of daily gridded sea surface temperature (SST) and sea ice concentration (SIC) from the Operational ...

Oscillatory behavior in Arctic sea ice concentrations
Journal of Geophysical Research: Oceans, 1996We have done a frequency analysis of the 9‐year record of sea ice concentrations obtained with the NASA Nimbus 7 scanning multichannel microwave radiometer (SMMR). Because of the periodic revisit time of the SMMR, we are able to examine recurrence of shorter‐period oscillations, as aliased by the revisit frequency, and longer‐period oscillations per se.

Comparison of digitized Canadian ice charts and passive microwave sea-ice concentrations
IEEE International Geoscience and Remote Sensing Symposium, 2003This paper presents results comparing digitized sea-ice charts with passive microwave estimates of sea-ice concentration using the NASA Team algorithm. The Canadian ice chart series contains detailed information on sea-ice type during the sea ice growth, consolidation and melt stages for four main ice-covered regions of Canada: the Canadian East Coast,

Estimation of sea ice concentration in the Sea of Okhotsk using PALSAR polarimetric data
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010The objective of this research is mainly in estimating sea ice concentration from Phased-Array L-band SAR (PALSAR) polarimetric data. This paper shows the results of estimating sea ice concentration from PALSAR data acquired from 2008 to 2010. The AMSR-E sea ice concentration data are also used to verify the result of sea ice concentration derived from

Monthly average polar sea-ice concentration
Data Series, 1995This data set represents the results of calculations carried out on sea-ice-concentration data from the SMMR and SSM/I instruments. The original data were obtained from the National Snow and Ice Data Center (NSIDC). The data set also contains the source code of the programs that made the calculations.
